## Generating Compound-Protein Interaction Descriptors

### Description

Generating Compound-Protein Interaction Descriptors

### Usage

    getCPI(drugmat, protmat, type = c("combine", "tensorprod"))

### Arguments

`drugmat` | The compound descriptor matrix.
`protmat` | The protein descriptor matrix.
`type` | The interaction type, one or two of `"combine"` and `"tensorprod"`.

### Details

This function calculates the compound-protein interaction descriptors by three types of interaction:

- `combine` - combine the two descriptor matrix, result has `(p1 + p2)` columns

- `tensorprod` - calculate column-by-column (pseudo)-tensor product type interactions, result has `(p1 * p2)` columns

### Value

A matrix containing the compound-protein interaction descriptors

### See Also

See `getPPI` for generating protein-protein interaction descriptors.

### Examples

    x = matrix(1:10, ncol = 2)
    y = matrix(1:15, ncol = 3)

    getCPI(x, y, 'combine')
    getCPI(x, y, 'tensorprod')
    getCPI(x, y, type = c('combine', 'tensorprod'))
    getCPI(x, y, type = c('tensorprod', 'combine'))
